1. h = distance from the axis of rotation to the center of mass Theoretical Derivation of the Period of a Physical Pendulum Period of a Physical Pendulum

2. Theoretical Derivation of the Period of a Physical Pendulum Small Angle Approximation For small θ h = distance from the axis of rotation to the center of mass For small angles a physical pendulum acts like an angular simple harmonic oscillator since the torque is proportional to the opposite of the angular position.

3. h = distance from the axis of rotation to the center of mass Period of a Physical Pendulum Theoretical Derivation of the Period of a Physical Pendulum But Angular frequency of a physical pendulum

4. Period of a Physical Pendulum h = distance from the axis of rotation to the center of mass Period of a Physical Pendulum Theoretical Derivation of the Period of a Physical Pendulum But

5. Period of a Physical Pendulum What if the physical pendulum is a simple pendulum of mass m and length L ? But So a simple pendulum is just a physical pendulum where all of the mass is at a distance L from the axis of rotation.
